These security issues were fixed:
- CVE-2017-7228: Broken check in memory_exchange() permited PV guest
 breakout (bsc#1030442).
- XSA-206: Unprivileged guests issuing writes to xenstore were able to
 stall progress of the control domain or driver domain, possibly leading
 to a Denial of Service (DoS) of the entire host (bsc#1030144).
- CVE-2016-9603: A privileged user within the guest VM can cause a heap
 overflow in the device model process, potentially escalating their
 privileges to that of the device model process (bsc#1028655).
- CVE-2017-6414: Memory leak in the vcard_apdu_new function in card_7816.c
 in libcacard allowed local guest OS users to cause a denial of service
 (host memory consumption) via vectors related to allocating a new APDU
 object (bsc#1027570).
- CVE-2017-6505: The ohci_service_ed_list function in hw/usb/hcd-ohci.c
 allowed local guest OS users to cause a denial of service (infinite
 loop) via vectors involving the number of link endpoint list descriptors
 (bsc#1028235).
- CVE-2017-2633: The VNC display driver support was vulnerable to an
 out-of-bounds memory access issue. A user/process inside guest could use
 this flaw to cause DoS (bsc#1026636).
These non-security issues were fixed:
- bsc#1022555: Timeout in 'execution of /etc/xen/scripts/block add'
- bsc#1029827: Forward port xenstored");
